The use of mechanical pressure gauges as pressure measuring devices is regulated by standard documentation. Also, manometric tubular springs - the sensitive elements of pressure gauges are used in various technology fields. Thus, the use of MTS in agricultural machinery allows reducing the traction resistance of tillage machines due to the effect of vibration when interacting with the soil, as well as improving the quality of the soil treatment process by adjusting the stiffness of the rack. This paper presents the results of calculating the stresses and deformations of the ripper shank structure, made in the form of a flexible tubular element when loaded with internal pressure and external force. The active development of the oil and gas industry is currently directed towards the remote territories of the Yamal peninsula and the territories of the Far East, which are characterized by complex natural and climatic conditions of construction. In this regard, it is necessary to develop new approaches and methods of construction in permafrost conditions. The paper presents the results of calculating the stresses and deformations of the structure of the ripper shank, made in the form of a flexible tubular element under loading by internal pressure and external force. The finite element method implemented in the "ANSYS" program was used for research.
